Has anyone used one of these for working on a C3? Any feedback would be greatly appreciated as I am contemplating getting one to do a transmission change. Thanks!
Some of those on the MidEngineCorvetteForum have used them. You just need to be sure that it's the correct length for your lift points. Be a lot easier than ramps.

The QuickJack is probably the best thing I ever bought for the car!
I was a bit late in getting one, when I first asked about them it seemed the whole world already had one!😀 I bought the 5000 version, (the smaller one is borderline for the weight of a Corvette). I didn't go with the extra long version, the standard 5000 is perfect.
The Quickjack website has videos showing how they work etc, which are accurate. The only thing I would say is that they are heavy. In the videos, the chap moves them around as though they weigh about 5 lbs - they don't! If you have s[pace to leave them under the car, that will be handy. I have to move mine and I ended up buying a little "dolly" that has casters for moving furniture and that allows me to manoeuvre them much more easily.
Because I have to "set them up" each time I use them it adds a bit of time, but I think I save three times that on many jobs!
There are explicit instructions regarding the initial fitting of the connections etc and they need to be followed to the letter. You'l also need hydraulic fluid, I bought mine from QuickJack. The lift comes with two sizes of rubber blocks that the car is supported on. I found that the smaller ones were just a bit low and the central chassis cross member was resting on the QuickJack, so I use the thicker blocks and its perfect. On a car with the stock ride height it slides under with plenty of room to spare.
It took a couple of uses to get used to where the ribber blocks need to be positioned, but now I have marked the lift and know where it needs to be in relation to the car, so it takes just a few minutes to get right.
I'd have liked a 4 post lifft, but I have limited ceiling height, so the QuickJack is perfect.
